The Australian National University (ANU) operates a quantum random number generator (QRNG) that produces true random numbers by measuring quantum fluctuations of vacuum^[1]. The system generates random bits at 5.7 Gbits/s and makes them freely available through both a web interface and API^[2].

Unlike traditional pseudorandom number generators that rely on mathematical algorithms and seeds, ANU’s QRNG creates genuine randomness by detecting quantum phenomena - specifically the electromagnetic field fluctuations that occur in a vacuum due to zero-point energy^[1:1].

The service offers multiple ways to access the random numbers:

• Direct web interface for visualization and downloads
• JSON API for programmatic access
• Pre-generated random number files up to 5GB in size
• Integration libraries for various programming languages including Python, R, Java, and .NET^[2:1]

The QRNG has practical applications in:

• Generating cryptographic keys
• Randomized clinical trials
• Computer game simulations
• Password generation
• Weather prediction modeling^[2:2]

The technical implementation is documented in peer-reviewed physics journals, with the quantum random number generation process detailed in Applied Physics Letters and Physical Review Applied^[1:2].
